===Culture===

We stopped overnight cultures at 11:10 and took out 30&micro;l culture from each test tube, and added it to 3ml fresh medium which is same for overnight culture. They are grown at 37&#x2103; from 11:10-14:10. After 3-hours culture, OD600 of each culture were measured. Because we found that the 3-hours culture of the sample KRX had not grown, we use the overnight culture of the sample KRX in later procedures. We took out 1ml medium from test tubes and put them into 1.5ml tubes and freeze them. The data is shown in table below.
 
-
===Measure===
 
-
We melt samples and centrifuge them at 14,000rpm, at 4&#x2103;, for 2min. Discard the supernatant and 150&micro;l cel lysis reagent to each pellet. These pellets were dissolved by vortex for 2min and centrifuged for 2min. From each tubes, 100&micro;l of the supernatant was took out and added to each well of the plate for the plate reader. 100&micro;l cell lysis reagent was also added to them. We measured GFP fluorescence in each sample (Ex/Em = 485/535nm, 1sec). The data is shown in table below.
 
-
We calculated the promoter activity and the results are shown in table below.

===Make Supplemented M9 Medium===

===Make Supplemented M9 Medium===
 
-
M9 salts were added to 1l MilliQ and sterilized by autocrave. We changed amount of CaCl<sub>2</sub> from 0.1mol/l (final concentration) to 0.01mmol/l (final concentration), and we could make supplemented M9 medium.
 
-
===Overnight culture===
 
-
The ML, i.e., E.coli KRX transformed with <partinfo>K358000</partinfo> was grown in the supplemented M9 medium including 1mmol/l IPTG for a night (16h).

===Culture===
 
-
OD600 of the overnight culture was measured. The overnight culture was diluted in fresh supplemented M9 medium including 7 different IPTG concentration and OD600 of each medium was measured every 4 hours. The samples to measure fluorescence of GFP were also collected (To know more detail procedures, see [[Team:Kyoto/Protocols#Measurement|Protocols]]).

We did not calculate RPU from these data because GFP fluorescence at 3.5h was lower than that at 3h in most of the samples, and we couldn't calculate GFP synthesis rate.

We think this is because GFP synthesized in overnight culture with IPTG 1mM had stayed more at 3h than 3.5h.

We think that lactose in the supplemented M9 medium come from casamino acids, so we decide to measure RPU of the lactose promoter without casamino acids because lactose in medium induces the lactose promoter.

We can't use the data of IPTG 0mM to calculate RPU because GFP fluorescence at 3.5h is lower than that at 3h. Also we can't use the data of ML-B 0.01mM IPTG and the data of MS-A of 0.03mM. Although GFP fluorescence of 0.1mM (20 September) at 3.5h is higher than that at 3h, OD600 is so low. Accordingly,  We can't use the data of 0.1mM (20 September).

CV of RPU of 0mM IPTG and that of 0.01mM IPTG is high. In addition, the supplemented M9 medium used in the experiment includes 0.01mM lactose. The RPU of the lactose promoter induced by IPTG only must be lower than the data resulted from this experiment.
